The plurality of hall call buttons 3 are provided in a plurality of hall, not shown, respectively.

The car 4 is provided in the hoistway. The car 4 is supported by the main ropes 2.

The car 4 includes a car door 5, a landing device 6, a lighting device 7, an intercom 8, a door motor 9, a door inverter 10, and a car equipment control device 11.

The car door 5 is provided at an entrance of the car 4. The car 4 is provided so as to be capable of opening and closing an entrance of the car 4. The stopping device 6 is provided to be able to detect whether the car 4 is stopped at an appropriate position on each floor. The lighting device 7 is provided so as to illuminate the interior of the car 4. The interphone 8 is provided so as to be usable when a user inside the car 4 communicates with the outside.

The door motor 9 is provided so as to be capable of generating a driving force for opening and closing the car door 5. The door inverter 10 is provided so as to be able to convert the input electric power and supply the converted electric power to the door motor 9.

For example, the car equipment control device 11 includes a door control unit 12, an emergency control unit 13, a door control power generation unit 14, an emergency control power generation unit 15, and a power switching unit 16.

The gate control unit 12 is provided so as to be able to control the gate inverter 10. The emergency control unit 13 is provided so as to be able to control the door control unit 12 in the energy saving mode. The door control power supply generating unit 14 is provided so as to be able to function as a power supply for operating the door control unit 12. The emergency control power supply generating unit 15 is provided so as to be able to function as a power supply for operating the emergency control unit 13. The power supply switching unit 16 is provided to be able to switch the supply source for supplying power to the floor stopping device 6.

The control device 17 is provided in a hoistway or a machine room. The control device 17 is arranged to be able to control the elevator as a whole.

The control device 17 includes a hoisting machine inverter 18, a disconnecting unit 19, an energy saving mode control unit 20, an elevator control unit 21, a control power generation unit 22, an emergency battery 23, and a battery charging unit 24.

The hoisting machine inverter 18 is provided so as to be able to convert electric power from the power source P and supply the converted electric power to the hoisting machine 1. The cutting unit 19 is provided to be able to cut off the power from the power source P when turned on. The energy saving mode control unit 20 is configured to be able to open the shut-off unit 19 when receiving the energy saving mode command. The elevator control unit 21 is provided so as to be able to control the elevator as a whole. The control power generation unit 22 is provided so as to be able to function as a power source for operating the elevator control unit 21. The emergency battery 23 is provided so as to be able to temporarily supply electric power to the elevator when the supply of electric power from the power source P to the elevator is cut off. The battery charging unit 24 is provided so as to be able to control charging of the emergency battery 23 using the power source P.

When the elevator is operated, the plurality of hall call buttons 3 transmit signals using power from the power source P, respectively. The elevator control unit 21 registers a landing call of the floor on which the landing call button 3 is operated, using electric power from the power source P, based on the signal. The elevator control unit 21 controls the hoisting machine inverter 18 so that the car 4 is directed to the floor, thereby controlling the rotation of the hoisting machine 1. The main rope 2 moves following the rotation of the hoisting machine 1. The car 4 is lifted up and down to the floor following the movement of the main rope 2.

Then, after the elevator control unit 21 transmits the normal mode door opening/closing command, the door control unit 12 controls the door inverter 10 to control the rotation of the door motor 9. The car door 5 is opened and closed following the rotation of the door motor 9.

When no call of the elevator is registered for a predetermined time, the elevator control unit 21 shifts the operation mode of the elevator to the energy saving mode. At this time, the elevator control unit 21 transmits an energy saving mode command and an energy saving mode transition preparation command.

The energy saving mode control unit 20 opens the shut-off unit 19 in response to the energy saving mode command. As a result, the power supply from the power source P to the elevator is cut off.

The door control unit 12 transmits the energy saving mode transition preparation instruction to the emergency control unit 13. The emergency control unit 13 receives the power supply from the emergency battery 23 by controlling the power supply switching unit 16 in accordance with the energy saving mode transition preparation instruction. Then, the emergency control unit 13 transmits a power saving mode transition completion signal. The door control unit 12 transmits the energy saving mode transition completion signal to the elevator control unit 21.

When any one of the plurality of hall call buttons 3 is operated in a state where the power supply from the power source P is cut off in the power saving mode, the hall call button 3 transmits a signal using the power from the emergency battery 23. The energy saving mode control unit 20 starts restarting the control device 17 by using the electric power from the emergency battery 23, and closes the shut-off unit 19, based on the signal.

At this time, the emergency control unit 13 also receives a signal from the hall call button 3. Based on the signal, the emergency control unit 13 determines whether or not the floor on which the hall call button 3 is provided is the same as the floor on which the car 4 is stopping, using the electric power from the emergency battery 23. When the floor provided with the hall call button 3 is the same as the floor where the car 4 is stopping, the emergency control unit 13 transmits a door opening command. The door control unit 12 opens the car door 5 in response to the door opening command. As a result, before the restarting of the control device 17 is completed, a landing door, not shown, is also opened at the floor where the landing call button 3 is provided.

Next, a method of detecting the operated hall call button 3 will be described with reference to fig. 2.

Fig. 2 shows the detection signal in the energy saving standby and the detection signal when the landing call button 3 of the 1 to 15 layers is operated. As shown in fig. 2, the landing call buttons 3 of 1 to 15 layers transmit mutually different binary signals when operated. Specifically, the detection signal in the energy saving standby and the detection signal when the landing call button 3 of 1 to 15 layers is operated show the H level or the L level on 4 signal lines. At this time, there are 16 patterns of combinations of H level or L level on the 4 signal lines so that it is possible to distinguish between in the energy saving standby and when the landing call button 3 of 1 to 15 layers is operated, respectively. As a result, the car equipment control device 11 and the control device 17 can detect the hall call button that has been operated.

Next, the operation of the control device 17 will be described with reference to fig. 3.

In step S1, the control device 17 determines whether or not a condition for shifting the operation mode of the elevator to the energy saving mode is satisfied. When it is determined in step S1 that the condition for shifting the operation mode of the elevator to the energy saving mode is not satisfied, the control device 17 performs the operation of step S1. When the condition for shifting the operation mode of the elevator to the energy saving mode is satisfied, the control device 17 performs the operation of step S2.

In step S2, the control device 17 cuts off the supply of electric power from the power supply to the elevator. Then, the control device 17 performs the operation of step S3. In step S3, the control device 17 determines whether any of the plurality of hall call buttons 3 is operated.

When it is determined in step S3 that any one of the plurality of hall call buttons 3 is not operated, the control device 17 performs the operation of step S3. When it is determined in step S3 that any one of the plurality of hall call buttons 3 is operated, the control device 17 performs the operation of step S4.

In step S4, the control device 17 restarts itself. Then, the control device 17 performs the operation of step S1.

Next, the operation of the car equipment control device 11 will be described with reference to fig. 4.

In step S11, the car equipment control device 11 determines whether or not an energy saving mode transition preparation instruction is received from the control device 17. When it is determined in step S11 that the energy saving mode shift preparation instruction from the control device 17 is not received, the car equipment control device 11 performs the operation of step S11. When it is determined in step S11 that the energy saving mode shift preparation command is received from the control device 17, the car equipment control device 11 performs the operation of step S12.

In step S12, the car equipment control device 11 establishes supply of electric power from the emergency battery 23. Then, the car equipment control device 11 performs the operation of step S13. In step S13, a power saving mode transition completion signal is transmitted to the control device 17.

Then, the car equipment control device 11 performs the operation of step S14. In step S14, the car device control apparatus 11 determines whether or not any of the plurality of hall call buttons 3 is operated. When it is determined in step S14 that any one of the plurality of hall call buttons 3 is not operated, the car device control device 11 performs the operation of step S14. When it is determined in step S14 that any one of the plurality of hall call buttons 3 is operated, the car device control apparatus 11 performs the operation of step S15.

In step S15, the car equipment control device 11 determines whether or not the floor on which the operated hall call button 3 is provided is the same as the floor on which the car 4 is stopping. When it is determined in step S15 that the floor on which the operated hall call button 3 is provided is not the same as the floor on which the car 4 is stopping, the car equipment control device 11 performs the operation of step S14. When it is determined in step S15 that the floor on which the operated hall call button 3 is provided is the same as the floor on which the car 4 is stopping, the car equipment control device 11 performs the operation of step S16.

In step S16, the car apparatus control device 11 opens the car door 5. Then, the car equipment control device 11 ends the operation.

According to embodiment 1 described in the foregoing, when the floor on which the hall call button 3 is provided is the same as the floor on which the car 4 is stopping, the car apparatus control device 11 opens the car door 5 before the restart of the control device 17 is completed. Therefore, the car 4 positioned in front of the eyes of the user can be opened from the energy saving mode in a short time at any floor.

In addition, when the floor provided with the hall call button 3 is not the same as the floor where the car 4 is stopping, the car device control apparatus 11 does not open the car door 5. Therefore, the car door 5 can be suppressed from being opened uselessly.

The car equipment control device 11 determines the floor on which the car 4 is stopping, using the electric power of the emergency battery 23, in a state where the electric power supply from the power source P is cut off. Therefore, the floor at which the car 4 is currently stopping can be more reliably determined.

In addition, the car apparatus control device 11 opens the car door 5 using the electric power from the power source P before the restart of the control device 17 is completed. Therefore, the power consumption of the emergency battery 23 can be suppressed.

Further, the plurality of landing call buttons 3 respectively transmit mutually different binary signals. Therefore, the operated hall call buttons 3 can be detected with the number of wirings smaller than the number of hall call buttons 3.

In addition, the lighting device 7 may be turned on by using the electric power from the power source P when the elevator is running. When the power supply from the power source P is cut off, the lighting device 7 can be turned off. Then, when a signal is transmitted using the electric power from the emergency battery 23 due to the operation of any one of the plurality of hall call buttons 3, the lighting device 7 may be turned on before the completion of the restart of the control device 17. As the electric power at this time, electric power from the power source P can be used. In this case, not only can the car 4 positioned in front of the eyes of the user open the car door 5 from the energy saving mode in a short time, but also the interior of the car 4 can be made bright.

Next, an example of the main part of the control device 17 will be described with reference to fig. 5.

The functions of the main part of the control device 17 can be implemented by a processing circuit.

At least one of the software and the firmware is described as a program. At least one of the software and firmware is stored in at least one memory 100 b. The at least one processor 100a implements the functions of the main part of the control device 17 by reading out and executing a program stored in the at least one memory 100 b. The at least one processor 100a is also referred to as a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, a DSP.

In the case of a processing Circuit provided with at least one dedicated hardware 200, the processing Circuit is implemented, for example, by a single unit, a complex unit, a programmed processor, a parallel programmed processor, an ASIC (Application SPECIFIC INTEGRATED Circuit), an FPGA (Field Programmable GATE ARRAY field programmable gate array), or a combination thereof. For example, the functions of the main part of the control device 17 are realized by processing circuits, respectively. For example, the functions of the main part of the control device 17 are realized collectively by a processing circuit.

Regarding the functions of the main part of the control device 17, one part may be realized by dedicated hardware 200, and the other part may be realized by software or firmware. For example, the functions of the elevator control unit 21 may be realized by a processing circuit that is dedicated hardware 200, and the functions other than the functions of the elevator control unit 21 may be realized by at least one processor 100a reading out and executing a program stored in at least one memory 100 b.

Thus, the processing circuit implements the functions of the main part of the control device 17 by means of hardware 200, software, firmware, or a combination thereof.

Although not shown, the functions of the main part of the car equipment control device 11 are also realized by a processing circuit equivalent to the processing circuit realizing the functions of the main part of the control device 17.
